The recently implemented court decision to break up Bell (=American Telephone & Telegraph Co.) to accord with U.S. anti-trust laws represents a highly significant policy decision which is proving to be influential in other countries as well as the U.S. The telecommunication industry is of such...

This paper documents the recent emergence of generalized networks as a fundamental computer-based planning tool and demonstrates the power of the associated modeling and solution techniques when used together to solve real-world problems. The first sections of the paper give a non-technical...

This paper analyzes the pattern of periodic reinvestments in depreciable assets when the amount of reinvestment in each period is set equal to the amount of depreciation for the period and derives a constant to which the periodic investments converge. The expression for the constant which...

Conventional accounting measures wealth W (assets and liabilities) and accounts for its net change, W(t + 1) - W(t), by means of income \Delta W(t), classified into various revenue and expense items. Proposed "momentum accounting" measures income momentum W\dot = dW/dt (time rate at which income...

In a recent paper [Bowman, V. J., C. S. Colantoni. 1973. Majority rule under transitivity constraints. Management Sci. 19 (9, May) 1029-1041.] Bowman and Colantoni have described an optimization model which they relate to problems of majority voting in the theory of social choice. Their...

The paper presents a new approach to solving a class of combinatorial economic allocation problems. One member of this class is known as the quadratic assignment problem. Besides presenting an algorithm to solve this problem, we will discuss in general terms the techniques for treating...

This paper considers a class of algorithms for solving quadratic programming problems. An attempt is made to rank the various procedures. Computational results are given and a discussion of the results is presented.

This paper gives efficient methods for solving four specially structured network problems that arise in connection with certain integer programming methods developed by Cook and Cooper, Hillier, and Glover. Such problems have also independently been studied in inventory theory by Ignall and...

A variety of combinatorial problems (e.g., in capital budgeting, scheduling, allocation) can be expressed as a linear integer programming problem. However, the standard devices for doing this often produce an inordinate number of variables and constraints, putting the problem beyond the...

A cardinality-constrained TSP (CC-TSP) problem requires the salesman to visit at least L and at most U cities, represented by nodes of a graph. The objective of this problem is to maximize the sum of weights of nodes visited. In this paper we propose a tabu search method based on ejection chain...
